This is just for historical reasons. Before, we have loongson2e machines
named as fulong(from loogson2f, changeed to fuloong) merged into main
kernel.

I suggest we might as well change fulong to fuloong2e, while call 2f based
fuloong fuloong2f (or something similar, you get the idea).
Because, fulong and fuloong are almost indistinguishable, neither on spelling
nor on pronunciation.

Yes， We will rearrange the directory structure and make they share the
common code.

Of course, we can deal with fulong(2e) later. However, I strongly suggest we get
fuloong2f right in the first place.
